# Differentiate log

Let u = log(1 + x2) and v = tan–1x.

We need to differentiate u with respect to v that is find .

On differentiating u with respect to x, we get We know  [using chain rule] However, and derivative of a constant is 0.   Now, on differentiating v with respect to x, we get We know  We have    Thus, Rate this question :
